The interrupting capacity reaches 330 kA at 240 V, stepping down to 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V. That SCCR headroom means it can be placed upstream in high-fault panels without cascading coordination issues. The trip delay is adjustable between 4 s and 17 s, giving the commissioning engineer room to coordinate with downstream motor-start curves. Maximum power loss is 37.5 W — relevant for enclosure thermal budgeting in a packed panel.
Those dimensions are standard for the 3VA2 frame at this rating — it occupies the same footprint as other 250 A 3-pole variants in the series. Width of 138 mm means it fits a standard 3-pole cutout in a distribution board without special adapters.
